BOLD-FACED-SLUG-CASTING ATTACHMENT FOR LINOTYPE MACHINES.

Application filed August 26, 1922. Seria1 No. 584,476.

Be it known that we. \YILMAM Encan Z01.- MAX and ANnnrw \V. Bnansnaw, citizens of the United States, residin at Farmington, in the countyof St. Francois and State of Missouri. have invented certain new and useful Improvements in Bold- Faced-Slug-(asting A ttachments for Linotype Machines, of which the following is a specification. reference being had to the accompanying (.lrawings.

This invention relates to type casting 111achines. such as the linotype machines described in the l\lergenthalcr patents, Nos. 36,531 and 4136.532. and particularly to means for bringing the line of matrices into proper relation to the mold so that holdfaced slugs may be cast from matr1ces assembled in light faced position in the assembler of the type setting machine.

In linotype or intertype machines of this character the line of matrices composed upon the assembler is shifted to the -asting mechanism by a carrier comn ionly known as the first elevator, and the purpose of the' present invent-ion is to vary the. movement of the carrier in bringing the line into proper relation to the mold to thus cause the alignment of any matrix for bold faced cast or type. that will align for the light faced east. In linotype machines as now on the market this is impossible from worn matrices.

A further object is to provide an attachment adapted to be applied beneath the elevator cap which may be.interposed between the adjusting screws of the elevator cap and the vise to thus prevent the elevator cap from descending as far as it ordinarily would descend, which attachment may be readily shifted out of such interposing position, and which attachment also includes an automatic safety pin which prevents the line of matrices from being shifted into operative position on the elevator cap it the. mats are thoughtlessly or carelessly as-,

sembled 011 the upper rail of the assembler instead of on the lower rail of the assemblcr when the attachment is thrown in use, this safety pin thus preventing any loss of time from a squirt that is sure to follow such neglect or carelessness.

Another object is to provide an attachment of this character which will cause the matricesto be. assembled on the fiber butler of the assembling elevator, which thus very materially reduces the wear to the lowe back lug of the matrix.

till another object is to provide an attachment t0 the elevator operating cam which shall increase the throw of the elevator operating cam and thus give increased motion to the elevator in its lift for alignment of matrices.

A further object is to provide a spring associated with the first elevator lever which is slightly weaker than the one now in use of a linotype machine showing the parts to which our improvement is to he applied; Figure 2 is a side elevation of. the same, showing the heel I) applied; to the cam B; Figure 3 is a perspective'view of the first to accommodate the extra action of the elev elevator and vise showing our improve-"' ment applied thereto;

In these dtawings. we have illustrated so much of a standard linotype machine as is necessary for an understanding of our invention, and in these drawingsA desi .nates the base of the machine, '13 t e main operatingcam which operates the elevator, C the elevator itself, I) the elevator cap, E the oppositely disposed rails of the elevator cap and in' wliich the matrices X slide, F designatesthe vise cap, G the stop screw carried by the elevator. H the rod or automatic which controls the clutch mechanism, and I the screw which normally engages this rod to actuate it. In ordinary circumstances and with matrices having plain faced type of ordinary font, the ole vator C descends until the stop screw G contacts directly with the vise cap F and the screw I with the rod E. The elevator is operatively connected by a link K to a lever L which is operatively controlled, as usual, by the. cam B. The matrices are assembled, as usual. upon either the upper rail or the lower rail of an assembler or assembling block M. The type are shifted from the assembler onto the rails E of the elevator cap in the usual manner. All these parts are such as are ordinarily found in .linotype or intertype machines and may be of any standard or ordinary construction.

Our attachment comprises an angular bracket 10 which is attached to the side wall of the elevator cap D, and pivoted to this bracket is a relatively thick rod or finger ll which is pivoted intermediate its ends but adjacent one end and which is adapted to be swung so as to carry the extremity of the long arm of the finger beneath the adjusting screw (i, the short arm of this linger l1 constituting a handle projecting beyond the, bracket 10 and forming means whereby this finger may be shifted from the dotted line position shown in Figiu'e 6 to its full line position and vice versa.

Attached to the finger 11 and extendmg approximately parallel thereto is a finger 12, the end of which is provided with a thickened portion 13, this finger being attached to the finger 11 by means of a screw 14 nd being provided with flanges 15 which embrace the finger 11. The thickened portion 13 at the extremity of the finger 12 is interposed between the adjusting screw I and the pin at the u per extremity of the clutch operating rod I when the finger 11 has its extremity interposed beneath the adjusting screw G and the upper face of the vise F. Vhen the finger 11 is swung to the dotted line position in Figure (3, the finger 12, of course. also moves to the dotted line position in Figure 6 and both fingers are actuated by the finger ll.

livotcd in a recess in the, end face of the finger 11 is a flat metal rod 16 which carries at its extremity a pivoted pin 17 which is pivoted for movement in a plane parallel to the plane of movement of the rod 16 and which passes through an opening in the side wall at the rail E. When the parts are shifted' 'to their operative position, as shown in full lines in Figure (3. this pin 1? projects into such position as to block or stop mat-' riees from entering the elevator it' these matrices are carelessly assembled on the upper rail M of the assembler. This pin prevents the machine from operating if the matrices are thoughtlcssly or carelessly assembled on' the upper rail of the assembler when the attachment is thrown in use. This prevents anypossible damage to the matrices so assembled and prevents loss of time t'romthe squirt which would other" wise be sure to follow such neglect. A stop it)" is formed on he bracket 10 to prevent arm 12 when out ot' ur'ic getting in the way of the elevator on dmvmvard stroke.

it will be understood by those acquainted with type setting machines of this character that this attachment causes and requires that the matrices, in order that the machine may operate properly, shall be assembled on the fiber buffer of the assembling elevator and this very materially reduces the wear on the lower back lug of each matrix. The interposition of the fingers 11 and 12 requires that a higher lift for alignment be given to the elevator in order to bring the matrices into proper position when casting bold face, and means must be provided for giving this increased motion to the ele-/ vator to align the matrices. To this end, we provide a shoe 18 which is adapted tr be at tached to and fit against the ronndt dw of the heel b of the elevator cam l3. Shoe 18 consists of a strip of IllGtfllllZLVlIlg i width slightly greater than that of the heel of the cam and curved to fit against the'heel, one end of the strip being thinned down so as to merge into the edge contour of the cam, this strip being held to the cam by means of a plurality of integral yokes or lugs 19 which extend upward on each side of the cam beyond the cut-out at the heel of the cam, each pair of lugs or yokes being apertured for the )assage of a transverse cross bar 20 througl i which passes a square headed adjusting screw 21. which binds against the inner face of the heel of the cam, as illustrated clearly in Figure 9, and draws the shoe 18 into close contact with the heel of the cam and holds it firmly in place. This shoe 18 increases the throw of the cam at its heel and thus increases the motion of the elevator in its lift for alignment of matrices.

in view of the increased motion given to the elevator, it is necessary to provide For this-incrtulscd motion at the link K. This link K, as illustrated in Figure 7, has the usual form of the ordinary link and is formed of a cylindrical member enclosing a. coiled spring 22. This spring illllllls against the upper end l of the link but bears at. its lower end against a head 23 which is enclosed within the cylindrical casing K, this head 23 supporting the lower-end of the spring and having a screw-tln'ea-ded aperture to engage the srrtwv-threaded end of the adjusting I-bolt it. This I-bolt connects with the end of the first elevator lever L in the usual manner. which elevator lever L is operated by the cam B, as usual. The spring 22 it will be-noted, is of the same construction as that ordinarily used but is somewhat weaker than the one now in use in order-to permit the extra lift for alignment when light face type is being cast, the elevator having its full dowmvard stroke. The spring 2'! takescare of the extra act-ion of the first elevator lever. When the elevator is in casting position. the lugs of the line of matrices are in the groove of the mold N which is carried. as usual, on the rotatable mold wheel 0. The lever under the action of the cam acts to lift the elevator to align the matrices, and under these circumstances the spring acts as a cushion.

In casting bold faced slugs from type assembled on the upper railof the assembler and delivered to theupper rail of the elevator jaw. it worn mat-s aroused the mats will not align properly and a zigzag line will result, due to the fact that some mats will be worn more than others. These mats are ordinarily worn on a lower corner, this being the point engaged by the elevator jaw to align the mats with a mold slot for bold faced cast. The wear of this part of the mat occurs in ordinary assembling. especially where the mats are assembled on the upper rail, which is of metal. For the light face line. mats are assembled on the lower rail of the assembler on a fiber buffer and deliv-' when assembled will never produce zigzag,

' li-ghtfaces when handled correctly by the machine. lVhere my invention is in use, the mats are assembled as for light face, and therefore. delivered to the lower position on the elevator jaw ,where they hang on the upper lug instead of resting on the lower lug when assembled for bold faced casting. The

vdownward stroke of the elevatorto casting position is stopped by member 11 so that the lugs of the mats enter into the upper grooves of the mold, the position for bold faced casting. The part 11 holds the eleva tor up instead of the mats being held up in the elevator to secure this bold faced position. i

In. the ordinary action of the elevator having its full downward stroke, after the mat lugs have entered thegroove of the mold there takes place an action for aligning the mats before thocast is made. This necessary lift for alignment action when the elevator is held up by member 11. The slightly weaker spring 22 on the connecting link is necessary because of this extra lift occasioned by the shoe 18 only in the ordinary casting of light face when elevator has full downward stroke.

\Ve claim 1. A bold-faced slug casting attachment for linotypes comprising a bracket adapt ed to be attached to the side wall of the elevator cap-on a level with the lower edge of said side wall, a lever pivoted adjacent one end to the bracket, the short arm of the lever constituting a handle projecting be yond the bracket and the extremity of the long arm being adapted to be disposed beneath the elevator cap and in alignment with the stop screw of the elevator cap, a finger attached to the lever and extending parallel thereto but terminating short of the endof said member and having at its extremity a thickened portion adapted to be disposed innnediately beneath and registering with the clutch operating screw of the cap, an arm carried by the member and projecting at an angle thereto, and a pin pivoted on said arm andadapted to extend through the side wall of the elevator cap and to be projected into the path of movement of the matrices if assembled on the upper rail when the lever and finger are disposed with their ends ,directly beneath said screws.

2. In a machine for casting type lines, a mold. an elevator having variable movement in relation thereto, means shift-able into position to limit the downward movement on the elevator and shiftable out of such position, a lever for shifting theelevator to align the matrices with the mold, av relatively deep spring operatively connecting the said lever with the elevator means for adjusting the tension of said spring, a cam for operating the lever and having alheel when operatively engaged wlth the lever to shift the elevator to bring the matrices in alignment with the mold. and a member detaehably engaged With the heel to increase .the throw of the heel to thereby add lift for alignment.
